Reef Endurance Sodium Bicarbonate is a pharmaceutical-based reef supplement that mixes crystal clear with no unwanted impurities. In reef aquaria, maintaining alkalinity within a range of 8.0-12.0dKH will enable corals and other reef-building invertebrates to grow properly. Sodium Bicarbonate is excellent for aquariums that have a naturally high pH. Unlike soda ash, sodium bicarbonate will have a slight lowering effect on your aquarium's pH. For best results, use in conjunction with Reef Endurance Calcium Carbonate as a two-part solution.
1gal RO/DI + 1.125 Cups of Sodium Bicarbonate
0.7ml/gallon of Calcium Bicarbonate Solution will raise calcium by approximately 0.5dKH. We do not recommend raising alkalinity by more than 0.5dKH per day.
Tip: If you are having issues raising your alkalinity levels, check and ensure your aquarium magnesium level is between 1200 and 1350ppm.
